摘要
针对高温化学气流冲刷烧蚀的使用状态,提出了等离子束流界面强化解决镀Cr层与基体结合强度不足的技术问题,用非转移等离子束流对镀铬钢件表面进行快速加热进行界面强化处理的工艺方法,介绍了等离子束流界面强化原理,进行了等离子束流强化工艺试验,并对试验结果进行了检测和分析研究,结果表明,镀Cr层与基体产生了冶金结合,较为显著地提高了镀层与基体的结合强度。
One technological problem about the weak combination of interface between Cr plating layer and substrate which was strengthened by plasma had been put forward according to the application state of under serious ablation and erosion by hot chemical airflow. The technology using distransfer plasma to heat the steel workpiece with Cr plating layer at high speed was used to strengthen interface bonding between Cr plating layer and substrate. The principle of strengthening with plasma was introduced in this paper and the process experiment of strengthening with plasma arc was carried out. The experimental results measurement and analysis show that the metallurgical bonding has occurred between Cr plating layer and substrate and the strengthening of interface bonding between Cr plating layer and substrate is improved remarkably.
